Heterachthes quadrimaculatus (Fabricius)

Heterachtes [sic] quadmnaculatus. — Aurivillius, 1912, p. 111. 



There may be some doubt as to the correct determination of this 

 species. The five specimens at hand have been compared with 

 material in the U.S. National Museum identified as quadrimaculata. 

 However, either two species are involved or a striking sexual dimor- 

 phism exists. The males are all densely pubescent with denuded 

 areas containing a coarse punctiu-e enclosmg a long erect seta and 

 the elytral apices are truncate and unarmed. In the females the 

 dense pubescence is less pronounced and the elytral apices bear a 

 stout spine at the external angle. Records include:
